normanna* DISTRIBUTOR.

Application led .Tune 24,

This invention relates to an oil distributor for the numerous bearings of the chassis of a vehicle and has for its object the pro vision of a device which ma be operated from the drivers seat and whereby all the bearings ofthe chassisy may be lubricated simultaneously with quantities of lubricant proportionate to the individual needs oi each bearing.

A further object of the invention is the provision of a device for distributing lubricant to the numerous bearings of the chassis l of a vehicle whenever desired by a .control from the drivers seat so that it will be unnecessary for the operator of the car to give individual attention to each bearing.

This invention will-be best understood from a consideration of the following detailed description, in view of the accompanying drawing forming apart ofthe specification; nevertheless it is to be understood that the invention is 4not confined to the disclosure, being susceptible of such vchanges and modifications which shall define no material au' principles 'of my invention.

Referring more particularly to the drawings, 1 designates a cylinder having an air chamber 2 above said cylinder and of larger diameter than the'cylinder. A closurel 3 'is 4secured to the to vof the air chamber and carries a vertical y disposed bracket 4 provided with a pulley 5 over which is entrained a cable 6. One end of said cable'is carried toa point adjacent to the drivers seat while the other end is secured to afpiston rod 7 movable in a stuffing box 8 formed in the cover 3.

the cylinder 1. The piston has an integrally formed upstanding circular flange 9 which forms with the inner wall of the cylinder an annular cu for elevating the oil in said cylinder. .f piston ring 10 is mounted in a groove in the piston to provide a snug lit for said piston in its cylinder.

An annular groove 11 is formed in' the wall of the cylinder at its lower end and 1s of such height to project slightly above the upper'perip eral edge of said piston to er. mit oil to pass from beneath the piston w en said piston is at its lowest position in the cylinder.

A drain opening 12 is provided in the bottom 1 3 o f the cylinder and is closed by a i plug 14. An'openin 15 is formed in the closure 3 for the admission of oil to the cyl-v inder and a plug 16 closes said opening.

A spring 17- surrounding the rod 7 engages at its lower end the pist-on 8 while the upper end is seated against the inner face of the closure 3 and resists the upward movement of said piston when the cable 6 is operated.

An air pipe 18 opens into the air chamber assage 19 is provided centrally of the rod .and has an opening 20 leading to the air chamber 2 and an opening 21 adapted to be placed. in communication with the-atmosphere when rmJ 7 is raised suiliciently A series of air chambers 22 form part of the exterior portion of the casting of the air chamber 2. There the cylinder 1 joins the wall of the air chamber 2 an annular v shoulder `23 is formed and provided with a series of oil pockets 24, a pocket being fur-- nished vfor each air cylinder 22.' A channel 25 connects each pocket ,with a passage 26 95n pipes 30 extending from the main distributor I provide an auxiliary distributor 31- having air chambers 32 in communication with oil pockets 33 formed in the upper end of the central portion 34 of the casting or .distributor v31. A channel 35 connects each pocket with an air. chamber. A spring pressed valve 36 in an enlargement of each channel controls the flow of air to the air chambers 32 and the oil through the passages 'to the, conduits 37 which are directed to the various bearings of the chassis of the vehicle.

Plugs 38 threaded into the air chambers 32 and plugs 39 threaded into the air chambers 22 are adapted to limit or increase the capacity of said chambers.

The air pipe 18 is connected with any suitable. source of air under pressure.

The operation of the device is as follows: l The plug 16 is removed and lubricating oil is supplied through the opening 15 to the cylinder 1 and on piston 8. Air at a predetermined pressure is supplied to the pipe 18 whenever desired and especially at the time when it is intended that the various bearings of the chassis are to be lubricated. The cable 6 is acted upon'and pis- 'oon 8 is elevated against the tension of the spring 17 whereby lubricating oil is raised and caused to i'ill the various pockets 24rat the shoulder 23. it must be borne in mind that when the piston 8 is raised suliiciently tli opening 21is placed in communication the atmosphere so that the air in chamber 2 is permitted to escape. As Soon the piston 8 is lowered and the passage 19 is closed to the atmosphere and sulficient 'ander pressure is admitted to chamber 2, the air will act upon the oil in the pockets 21 and upon the valves 27, opening the same, and causing the air to completely ll chambers 22.

Uil is forced down through the passage 26 andinto the conduits 30 whence it is carried to bearings to be oiled direct and to the pockets 33 in the auxiliary distributing device 3l which is shown in Figure 5. Air pressure operated in advance ott the oil will act upon. the valves 36 and cause the same to open with the air lilling the chambers 32. Continued pressure upon the valves will cause the oil to be discharged past said valves and into the conduits 35 and the air in the chambers 32 will act on said oil and cause the .same to be distriluited through the conduits 37 to the various bearings oi' the automobile.

Since all the bearings do not need the same quantity of lubricating oil the pockets 2iand may vary capacity and the springs Ll5 and 28 in the distributors may be varied in strength that where certain bearings do con alwa. ced predetern'iined- Quan" springs may bc made suihcienei resist a nredetcrn'iined air pre d tiereiiore rent excessive lubrication of certain parts. il/"hen it is desired, therefore, tolubricate such parts the air pressure may he increased fior eti'ectually forcing oilto sich bearings.

will be appreciated that the size of the bore of the feed line to certain bearings may also be sutiicicntly restricted to prevent excessive lubrication of certain bearings which do not require as much lubricating oil as others.

When the spring 17 returns the piston 8 to its lower inoperative position in the cylinder 1 the groove 11 permits the oil which is in the space around the center ofthe piston between the spokes, to flow under the outer rim of the piston into the space between the flange 9 and the cylinder wall when the oil is too low tolow over said flange.

The web 8a connects the piston 8 to the rod 7 to permit the oil in the container to pass freely through the piston when the piston is lowered or elevated so that the pis ton is not retarded by suction or compression. i
